If there’s nothing that annoys me more, it’s people cosplaying characters that they don’t essentially “get” their character’s personality. In other words, a friend that’s cosplaying a happy-go-lucky in your face type character (Haruhi Suzumiya, for example) but the cosplayer just remains dead-faced and nonchalant the whole time -.-
This mainly is an issue that comes up when you’re politely requesting photos of cosplayers, or just going to cons with friends who are also cosplaying. They just don’t seem to know how to truly “get into character” for whatever cosplay they’re doing. It’s because of situations like this that I have the firm belief that you should only cosplay characters where you really get their personality, understand their character, and, most importantly, know how to be your character. There’s no such thing as an emo Yukimura Genjiro Sanada (Sengoku Basara), it just doesn’t exist, so don’t cosplay him if you can’t get it right >.<*
I’m not saying that you should ‘be in character’ the entire con, but at least know how to strike a pose for pictures when the situation calls for it, which is easy to do if, you know, you know your character. You shouldn’t cosplay a character solely because they’re easy to cosplay & you have everything for that costume on hand already, you should really try to cosplay characters that, more or less, you actually like. I may have the ability & supplies to cosplay Shinji Ikari (Evangelion) easily, but Gendou Ikari or Ryouji Kaji (same series) would be easier characters to do personality & pose wise, for example.
In either case, you could also make up for this lack of understanding a character for a cosplay by doing research into their personality, watching clips of the show/game/whatever to see what types of poses they make, etc. so you can really get that character down, but it may also be more advantageous and easier to start out with cosplaying a character you know like the back of your hand and can “get into character” with with little to no effort.
The main thing to take away from this article is to really get to know your character before the con so you can actually be that character when the time comes, vs. totally ruining what may be an awesome cosplay with a crappy attitude/personality.
